Description

TECHNICAL FIELD [0001] The present invention relates to a rainwater collecting type superior treatment apparatus having a non-point pollutant removing function,

More particularly, the present invention relates to a rainwater collecting type superior treatment apparatus having a non-point pollutant removing function, and more particularly, to a rainwater collecting type rainwater collecting apparatus capable of purifying non-point pollutants, And a rainwater catching type stormwater treatment apparatus having a nonpoint pollutant removal function capable of reducing facility cost and maintenance cost.

Generally, non-point pollution source refers to a source of emission of water pollutants unspecified at unspecified places such as cities, roads, farmland, mountainous areas, construction sites, etc., and heavy metals and harmful organic substances are discharged from vehicles, At the time of rainfall, these materials are discharged in the form of road runoff in the form of stormwater through rainwater catches and streams to nearby water bodies such as rivers, which has a serious adverse effect on the aquatic ecosystem.

For example, the major source of heavy metals in urban areas is the transportation sector, and a large amount of lead (Pb), cadmium (Cd), chromium (Cr), copper (Cu), zinc (Zn) Of these, lead, cadmium, and chromium are particularly toxic carcinogens that are prescribed and managed as harmful substances of certain water quality.

PCBs, which are widely used as insulating oil for transformers, are persistent, biodegradable organic pollutants. The major sources are incinerators, transformer fabrication and installation sites, and incinerators in the form of DL-PCBs. PCBs are more dense than water and are adsorbed and accumulated in sediments of soils and streams due to their very low water solubility. In addition, organic solvent TCE widely used as a cleaning agent for metal machinery is a refractory organic compound frequently generated in the industrial area. Since the solubility at room temperature is as high as 1,100 mg / L, once it is discharged, it has a larger specific gravity than water, Are also designated as specific water hazardous substances.

On the other hand, a non-point pollutant abatement apparatus as disclosed in Korean Patent Registration No. 10-0911819 has been proposed as a method of treating a nonpoint pollutant source as described above.

1, the nonpoint pollutant abatement apparatus 10 includes an inlet 12, a first settling tank 100, a complex filtration tank 200, a second settling tank 300, and an outlet 14 Each of the first settling tank 100, the complex filtration tank 200, and the second settling tank 300 is provided with an opening / closing lid 16 capable of inserting or inserting therein, And the like, as shown in FIG.

The nonpoint pollutant abatement device 10 flows into the first sedimentation tank 100 through the inlet 12 so that the sediment in the nonpoint contamination material sinks down to the bottom of the first sedimentation tank 100 due to its own weight , The oil and the suspended matter rise, and the water is primarily separated from the water. Thereafter, the filtered water is introduced into the complex filtration tank 200 through the first settling tank 100 and the connection pipe 110 to pass through the first to fourth filtration layers 210, 220, 230 and 240 in a zigzag manner So that it flows into the second settling tank 300 for a long period of time and then flows into the second settling tank 300 through the outflow port 14 after being settled again so as to prevent water pollution in the public water or groundwater.

However, the above-mentioned conventional non-point pollutant abatement apparatus 10 is relatively large in size (volume and weight), requiring a large occupied space, requiring a large installation cost and requiring a long installation period.

In addition, the conventional non-point pollutant abatement device 10 described above is not only difficult to install due to various problems such as dismantling and re-installation of electric power cables, communication cables and sewer pipes buried in roads underground, There is a disadvantage that disputes or complaints are caused.

Hereinafter, the operation of the stormwater catching type stormwater treatment apparatus having the function of removing nonpoint pollutants according to the first embodiment of the present invention will be briefly described.

8A and 8B are diagrams for explaining the operation of the rainwater catch type sewage treatment apparatus having the non-point pollutant removing function according to the first embodiment of the present invention, wherein FIG. 8A is a cross- Fig. 8B is a longitudinal sectional view showing a state at the time of entering the storm.

First, a plurality of openable and closable members 5 are inserted into the fixed insertion holes 17 while the locking protrusions 513 are inserted into the fixed insertion holes 17 while inserting the closed portions 511 to seal the drain holes 16 of the case body 11 To the cartridge case (1). The filter cartridge 2 filled with the granular filter media is inserted into the cartridge receiving groove 15 of the case body 11 so that the flat surface of the filter cartridge 2 faces the segment projection 13 . After the plurality of cartridge cases 2 with the filter cartridge 2 assembled in this manner are installed, the filter net 6 is placed on top of the filter cartridge 2 and the rainwater receiver cover 4 is placed on the cartridge case 1 The assembling of the rainwater catching type good water treatment apparatus is completed.

When the stormwater collecting type sewage treatment apparatus assembled as described above is installed in the rainwater catching installation hole (not shown) formed in the drainage path of the roadside, when the rainwater catching cover 4 receives the rainwater through the rainwater catching cover 4, Is filtered by the filter net (6), and the bleed flows down through the curved surface of the first and second cartridge baskets (21, 22) and enters the inside through the filtration hole.

When the rainwater flows into the filter cartridge 2 as described above, the rainwater is brought into contact with the granular filter media, so that the adsorbing action of the non-point pollutants contained in the rainwater is performed, thereby removing the non-point pollutants and improving the water quality.

8B, the opening / closing part 51 is closed by the weight of the case main body 11 due to its own weight, as shown in FIG. 8B, since the rainwater passing through the inside of the filter cartridge 2 is discharged to the lower part of the cartridge- 11, the drainage hole 16 is opened while the fixing protrusion 513 is detached with reference to the fixing protrusion 513 fixed to the drainage hole 11, so that the drainage drops downward. At this time, the clip-shaped elastic portion 522 is expanded and expanded by the opening force of the opening / closing portion 52.

On the other hand, when rain does not flow through the rainwater catch cover 4, the weight load of the rainfall load on the opening / closing part 51 is eliminated, so that the elastic force of the elastic part 522, (51) is pulled to seal the drain hole (16). When the drain hole 16 is closed by the opening and closing member 5, even if stagnant water or sewage is spoiled in the inside of the drainage duct or odor is generated due to foreign matter, the drainage hole does not flow upward and the surrounding atmosphere around the drainage can be maintained comfortably .

The present invention is not limited to the above-described embodiment, but may be applied to other types of apparatuses such as a water pump, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
